Artificial Sweetener May Disrupt Body's Ability to Count Calories
Well, here's a study that explains everything. Apparently our bodies learn to count calories on their own and regulate our food intake based on qualities like sweetness. But artificial sweeteners confuse the body. It loses its reliable sweetness=calories connection, and all hell breaks loose.
Don't I know it. Since I started drinking more flavored beverages--as opposed to a strictly water, orange juice, or beer liquid regimen--my appetite has been out of sync with any actual calorie needs I have. While some of this represents eating out of boredom because I live in a suburban wasteland instead of a vibrant city and come home to an empty house at night due to the vagaries of work schedules, that can't account for my untold desire to eat. This study makes sense, though. I used to know restraint in my consumption of things like cookies. Today eating ten cookies doesn't sound crazy; neither does crumbling three Oreos into a couple scoops of ice cream every night after dinner. (Don't worry: I stopped buying ice cream.) It's not like I don't eat; the cereal consumption alone in our house would put most people to shame. It's like my body never says "stop," and if it does, it lasts about an hour. I ate enough chicken wings and cheese-covered fried potatoes last night that I should have been full until Sunday; by the time I got home an hour and a half later, I was staring into the freezer and thinking about food again.
Now I have a scapegoat. Damn you, diet lemonade. Out, out, damned diet iced tea! Be gone, heavenly mango tropical drink (only ten calories per can) and aspartame-sweetened salad dressings. I knew all along you might be giving me cancer, but I was OK with that--you were keeping me thin! But now you're making me fat AND giving me cancer? Hello, Sam Adams; goodbye, Diet Coke. If a beer with dinner can reteach my body to count its own calories, and perhaps make me too tired to shovel food into my mouth in the process, that's the drastic measure I'll have to take.

This study demonstrated that chronic aspartame consumption in rats can lead
to altered T-maze performance and increased muscarinic cholinergic receptor
densities in certain brain regions.
Control and treated rats were trained in a T-maze to a particular side and
then periodically tested to see how well they retained the learned response.
Rats that had received aspartame (250 mg/kg/day) in the drinking water for 3
or 4 months showed a significant increase in time to reach the reward in the
T-maze, suggesting a possible effect on memory due to the artificial
sweetener.
Using [(3)H]quinuclidinyl benzilate (QNB) (1 nM) to label muscarinic
cholinergic receptors and atropine (10(-6) M) to determine nonspecific
binding in whole-brain preparations,
aspartame-treated rats showed a 31% increase in receptor numbers when
compared to controls.
In aspartame-treated rats, there was a significant increase in muscarinic
receptor densities in the
frontal cortex, midcortex, posterior cortex, hippocampus, hypothalamus and
cerebellum of 80%, 60%, 61%, 65%, 66% and 60%, respectively.
The midbrain was the only area where preparations from aspartame-treated
rats showed a significant increase in Na(+),K(+)-ATPase activity.
It can be concluded from these data that long-term consumption of aspartame
can affect T-maze performance in rats and alter receptor densities or
enzymes in brain. PMID: 15159141
A Searle Laboratories team in 1976 reported that in 4 monkeys fed aspartame,
by 12 hours: "...the major fraction (70%) of the [aspartate] label appeared
in the expired air (Fig.6)...Urinary and fecal 14C [ aspartate derived ]
amounted to 4--6% of the administered [ aspartate ] label."
This gives a total of a maximum 76% excreted aspartate from the aspartame,
indicating that 24% of this excitotoxin was retained in the body. It is
reasonable to conclude that daily use of aspartame must lead to substantial
accumulation of this excitotoxin, aspartate, in body tissues.
Their 1979 review said: "Aspartame... is hydrolyzed in the gut to yield
aspartic acid, phenylalanine, and methanol....
Aspartate may also be incorporated into body constitutents such as other
amino acids, proteins, pyrimidines, asparagine, and N-acetylaspartic acid."

Aspartame (3-amino-N-(alpha-carboxyphenethyl) succinamic acid, methyl ester;
the methyl ester of aspartylphenylalanine, SC-18862) is hydrolyzed in the
gut to yield aspartic acid, phenylalanine, and methanol.
This review of the literature describes the metabolic paths followed by
aspartate in its conversion to CO2 or its incorporation into body
constituents.
About 70 percent of 14C from [asp-14C]-aspartame is converted in the monkey
to 14CO2.
Some of the aspartate is converted at the intestinal mucosal level to
alanine by decarboxylation.
This amino acid may be oxidized to CO2 by entering the tricarboxylic acid
cycle via pyruvate and acetyl CoA.
In addition, transamination of aspartate to oxaloacetate permits this
product also to enter the tricarboxylic acid cycle.
Aspartate may also be incorporated into body constitutents such as other
amino acids, proteins, pyrimidines, asparagine, and N-acetylaspartic acid.
It is concluded that the aspartate moiety of aspartame is metabolized in a
manner similar to that of dietary aspartic acid.

It is certain that high levels of aspartame use, above 2 liters daily for
months and years, must lead to chronic formaldehyde-formic acid toxicity.
Fully 11% of aspartame is methanol-- 1,120 mg aspartame in 2 L diet soda,
almost six 12-oz cans, gives 123 mg methanol (wood alcohol).
The methanol is immediately released into the body after drinking--
unlike the large levels of methanol locked up in complex molecules inside
many fruits and vegetables.
Within hours, the liver turns much of the methanol into formaldehyde, and
then much of that into formic acid, both of which in time are partially
eliminated as carbon dioxide and water.
However, about 30% of the methanol remains in the body as cumulative
durable toxic metabolites of formaldehyde and formic acid-- 37 mg daily,
a gram every month, accumulating in and affecting every tissue.
If only 10% of the methanol is retained daily as formaldehyde, that would
give 12 mg daily formaldehyde accumulation-- about 60 times more than the
0.2 mg from 10% retention of the 2 mg EPA daily limit for formaldehyde in
drinking water.
Bear in mind that the EPA limit for formaldehyde in drinking water is
1 ppm, or 2 mg daily for a typical daily consumption of 2 L of water.

This long-term low-level chronic toxic exposure leads to typical patterns of
increasingly severe complex symptoms, starting with headache, fatigue, joint
pain, irritability, memory loss, rashes, and leading to vision and eye
problems, and even seizures. In many cases there is addiction. Probably
there are immune system disorders, with a hypersensitivity to these toxins

They found that about 70% of the radioactive methanol in aspartame put into
the stomachs of 3 to 7 kg monkeys was eliminated within 8 hours, with little
additional elimination, as carbon dioxide in exhaled air and as water in
the urine.
They did not mention that this meant that about 30% of the methanol must
transform into formaldehyde and then into formic acid, both of which must
remain as toxic products in all parts of the body.
They did not report any studies on the distribution of radioactivity in body
tissues, except that blood plasma proteins after 4 days held 4% of the
initial methanol.
This study did not monitor long-term use of aspartame.
The low oral dose of aspartame and for methanol was 0.068 mmol/kg, about 1
part per million [ppm] of the acute toxicity level of 2,000 mg/kg, 67,000
mmol/kg, used by McMartin (1979).
Two L daily use of diet soda provides 123 mg methanol, 2 mg/kg for a 60 kg
person, a dose of 67 mmole/kg, a thousand times more than the dose in this
study.
By eight hours excretion of the dose in air and urine had leveled off at
67.1 +-2.1% as CO2 in the exhaled air and 1.57+-0.32% in the urine, so 68.7
% was excreted, and 31.3% was retained.
This data is the average of 4 monkeys.
"...the 14C in the feces was negligible."
"That fraction not so excreted (about 31%) was converted to body
constituents through the one-carbon metabolic pool."
"All radioactivity measurements were counted to +-1% accuracy..."
This indicates that the results could not be claimed to have a precision of
a tenth of a percent. OK, so this is a nit-pick-- but I believe espousing
spurious accuracy is a sign of scientific insecurity.
The abstract ends, "It was concluded that aspartame was digested to its
three constituents that were then absorbed as natural constituents of the
diet."
Thus, the concept is very subtly insinuated that methanol, as a
constituent of aspartame, is absorbed as a natural constituent of the diet.
"Dietary methanol is derived in large part from fresh fruits and
vegetables."
This is a serious error, since the large amounts of methanol in fresh fruits
and vegetables are not readily released by human digestion. (W. C. Monte,
1984)
Nowhere in this report are mentioned the dread words, "formaldehyde" and
"formic acid".
Of course, methanol and formaldehyde toxicity studies are highly relevant to
the issue of aspartame toxicity. [ Aspartame has to be turned into its
toxic products, formaldehyde and formic acid, in the body, before it is
toxic, so some pro-aspartame reseach studies test aspartame outside the
body, and then proclaim that they have proved that it is not toxic. ]

Elevated nitric oxide/peroxynitrite theory of multiple chemical sensitivity:
central role of N-methyl-D-aspartate receptors in the sensitivity mechanism.

University, Pullman, WA 99164, USA. martin_pall@wsu.edu
The elevated nitric oxide/peroxynitrite and the neural sensitization
theories of multiple chemical sensitivity (MCS) are extended here to propose
a central mechanism for the exquisite sensitivity to organic solvents
apparently induced by previous chemical exposure in MCS.
This mechanism is centered on the activation of N-methyl-D-aspartate (NMDA)
receptors by organic solvents producing elevated nitric oxide and
peroxynitrite, leading in turn to increased stimulating of and
hypersensitivity of NMDA receptors.
In this way, organic solvent exposure may produce progressive sensitivity to
organic solvents.
Pesticides such as organophosphates and carbamates may act via muscarinic
stimulation to produce a similar biochemical and sensitivity response.
Accessory mechanisms of sensitivity may involve both increased blood-brain
barrier permeability, induced by peroxynitrite, and cytochrome P450
inhibition by nitric oxide.
The NMDA hyperactivity/hypersensitivity and excessive nitric
oxide/peroxynitrite view of MCS provides answers to many of the most
puzzling aspects of MCS while building on previous studies and views of this
condition. PMID: 12948884
Prof. Pall describes processes by which an initial trigger exposure, such as
carbon monoxide or formaldehyde, can generate hypersensitivity to many
substances. He himself had recovered from a sudden, debilitating attack of
multiple chemical sensitivity in June/July 1997.

Abstract:
Adult male rats were given an oral dose of 10 mg/kg aspartame,
14C-labeled in the methanol carbon.
At timed intervals of up to 6 hours, the radioactivity in plasma and several
organs was investigated.
Most of the radioactivity found (>98% in plasma, >75% in liver) was bound to
protein.
Label present in liver, plasma and kidney was in the range of 1-2% of total
radioactivity administered per g or mL, changing little with time.
Other organs (brown and white adipose tissues, muscle, brain, cornea and
retina) contained levels of label in the range of 1/12th to 1/10th of that
of liver.
In all, the rats retained, 6 hours after administration, about 5% of the
label, half of it in the liver.
The specific radioactivity of tissue protein, RNA and DNA was quite uniform.
The protein label was concentrated in amino acids, different from
methionine, and largely coincident with the result of protein exposure to
labeled formaldehyde.
DNA radioactivity was essentially in a single different adduct base,
different from the normal bases present in DNA.
The nature of the tissue label accumulated was, thus, a direct consequence
of formaldehyde binding to tissue structures.
The administration of labeled aspartame to a group of cirrhotic rats
resulted in comparable label retention by tissue components, which suggests
that liver function (or its defect) has little effect on formaldehyde
formation from aspartame and binding to biological components.
The chronic treatment of a series of rats with 200 mg/kg of non-labeled
aspartame during 10 days results in the accumulation of even more label when
given the radioactive bolus, suggesting that the amount of formaldehyde
adducts coming from aspartame in tissue proteins and nucleic acids may be
cumulative.
It is concluded that aspartame consumption may constitute a hazard because
of its contribution to the formation of formaldehyde adducts. PMID: 9714421
[ Extracts ]
"The high label presence in plasma and liver is in agreement with the
carriage of the label from the intestine to the liver via the portal vein.
The high label levels in kidney and, to a minor extent, in brown adipose
tissue and brain are probably a consequence of their high blood flows (45).
Even in white adipose tissue, the levels of radioactivity found 6 hours
after oral administration were 1/25th those of liver.
Cornea and retina, both tissues known to metabolize actively methanol
(21,28) showed low levels of retained label.
In any case, the binding of methanol-derived carbon to tissue proteins was
widespread, affecting all systems, fully reaching even sensitive targets
such as the brain and retina....
The amount of label recovered in tissue components was quite high in all the
groups, but especially in the NA rats.
In them, the liver alone retained, for a long time, more than 2 % of the
methanol carbon given in a single oral dose of aspartame, and the rest of
the body stored an additional 2 % or more.
These are indeed extremely high levels for adducts of formaldehyde, a
substance responsible of chronic deleterious effects (33), that has also
been considered carcinogenic (34,47).
The repeated occurrence of claims that aspartame produces headache and other
neurological and psychological secondary effects-- more often than not
challenged by careful analysis-- (5, 9, 10, 15, 48) may eventually find at
least a partial explanation in the permanence of the formaldehyde label,
since formaldehyde intoxication can induce similar effects (49).
The cumulative effects derived from the incorporation of label in the
chronic administration model suggests that regular intake of aspartame may
result in the progressive accumulation of formaldehyde adducts.
It may be further speculated that the formation of adducts can help to
explain the chronic effects aspartame consumption may induce on sensitive
tissues such as brain (6, 9, 19, 50).
In any case, the possible negative effects that the accumulation of
formaldehyde adducts can induce is, obviously, long-term.
The alteration of protein integrity and function may needs some time to
induce substantial effects.
The damage to nucleic acids, mainly to DNA, may eventually induce cell death
and/or mutations.
The results presented suggest that the conversion of aspartame methanol into
formaldehyde adducts in significant amounts in vivo should to be taken into
account because of the widespread utilization of this sweetener.
Further epidemiological and long-term studies are needed to determine the
extent of the hazard that aspartame consumption poses for humans."

Dear Rich,
Thank you for the opportunity to say something about the "paper" by Tephly
that followed our study on the incorporation of aspartame-derived methanol
label into DNA and protein of rats.
I don't know if responding to that publication is worth the effort.
Surprisingly, a serious journal, such as Life Sciences published a rebuttal
of our previous paper as a normal "research paper", but including no new
information neither experimental work.
This is only a sample of the "scientific" power of the advocates of
aspartame.
Anybody can extract conclusions from this anomaly, but it seems to me that
there was nothing new in that pamphlet that may add information to what we
already explained in our paper.
The responses to the questions raised by Tephly are already in our paper,
which means that either that it was not read or, worst, it was misread.
The presence of aspartame-derived label in DNA and protein adducts is
unquestionable and unquestioned, and agrees with previous studies.
Then, what importance has the mechanism of incorporation?
There were adducts, and they represent loss of function and mutation.
That was our thesis.
The reference to previous studies showing very low levels of formaldehyde in
blood do not refute our data.
First of all, measuring formaldehyde is tricky,
and in any case, the circulating levels would be below the current limit of
detection for most of the methods used.
That is the current explanation for the low levels of methanol in plasma
after aspartame loading: they are zero, using most of the methods available
for methanol, since the expected levels are currently below the limit of
detection...
In addition, it is not logical to expect to find measurable levels of
formaldehyde in a medium (blood) containing a huge amount of protein.
Formaldehyde reacts immediately with proteins because it is highly reactive:
that is the reason why we have found it in cell protein and DNA.
It is absurd to expect it to forfeit binding with cell proteins and go all
the way into the bloodstream!
Remember that formaldehyde is used to preserve corpses precisely because it
binds protein (including those of putrefactive bacteria) and prevents its
degradation.
The "alternative" point expressed by Tephly, suggesting that aspartame
methanol-label goes all the way into formic acid and the C1 pathway was
thoroughly refuted by us, using experimental data.
There was no labelled methionine nor thymine in protein and DNA respectively
in the rat protein we recovered from rats treated with aspartame.
This means--unequivocally-- that the label present in DNA and protein
adducts was NOT incorporated into amino acids or nucleic acid bases.
The only explanation for our data was that the label was in the form of
formaldehyde adducts.
If this explanation does not satisfy other scientists, they are free to
repeat the experiment and show where we went wrong, or to probe and prove
experimentally their hypotheses. Otherwise, our results stand unchecked
and, consequently, should be deemed true.
I hope that this information will help any attentive reader understand why
we have left for good this field of study.
Best regards.

A recent paper by Trocho et al. (1) describes experiments meant to show that
formaldehyde adducts are formed when rats are administered the sweetener
aspartame.
These authors assume that the methanol carbon of aspartame generates
formaldehyde which then forms adducts with protein, DNA, and RNA.
Doses employed range widely.
In this letter, studies which have been published previously and which were
not cited by these authors are reviewed in order to put into perspective the
disposition of methanol and formaldehyde in monkeys and humans, species
relevant to the toxicity of methanol and its toxic metabolite, formic acid.

Under tested experimental conditions, methyl alcohol and ethyl alcohol
were demonstrated to be carcinogenic for various organs and tissues.
They must also be considered multipotential carcinogenic agents.

tumors of the oral cavity, tongue, and lips.

Surely the authors deliberately emphasized that aspartame is well-known
to be a source of formaldehyde, which is an extremely potent, cumulative
toxin, with complex, multiple effects on all tissues and organs.
This is even more significant, considering that they have already tested
aspartame, but not yet released the results:

We determined the genotoxicity of 39 chemicals currently in use as food
additives.
They fell into six categories-dyes, color fixatives and
preservatives, preservatives, antioxidants, fungicides, and sweeteners.
We tested groups of four male ddY mice once orally with each additive at
up to 0.5xLD(50) or the limit dose (2000 mg/kg) and performed the comet
assay on the glandular stomach, colon, liver, kidney, urinary bladder, lung,
brain, and bone marrow 3 and 24 h after treatment.
Of all the additives, dyes were the most genotoxic.
Amaranth, Allura Red, New Coccine, Tartrazine, Erythrosine, Phloxine, and
Rose Bengal induced dose-related DNA damage in the glandular stomach, colon,
and/or urinary bladder.
All seven dyes induced DNA damage in the gastrointestinal organs at a low
dose (10 or 100 mg/kg).
Among them, Amaranth, Allura Red, New Coccine, and Tartrazine induced
DNA damage in the colon at close to the acceptable daily intakes (ADIs).
Two antioxidants (butylated hydroxyanisole (BHA) and butylated
hydroxytoluene (BHT)), three fungicides (biphenyl, sodium
o-phenylphenol, and thiabendazole), and four sweeteners (sodium
cyclamate, saccharin, sodium saccharin, and sucralose) also induced DNA
damage in gastrointestinal organs.
Based on these results, we believe that more extensive assessment of
food additives in current use is warranted. PMID: 12160896

The genotoxicity of steviol, a metabolite of stevia extract, was evaluated
for its genotoxic potential using the comet assay.
In an in vitro study, steviol at 62.5, 125, 250, and 500 micrograms/ml did
not damage the nuclear DNA of TK6 and WTK1 cells in the presence and absence
of S9 mix.
In vivo studies of steviol were conducted by two independent organizations.
Mice were sacrificed 3 and 24 hr after one oral administration of steviol at
250, 500, 1000, and 2000 mg/kg.
DNA damage in multiple mouse organs was measured by the comet assay as
modified by us.
After oral treatment, stomach, colon, liver, kidney and testis DNA were not
damaged.
The in vivo genotoxicity of stevia extract was also evaluated for its
genotoxic potential using the comet assay.
Mice were sacrificed 3 and 24 hr after oral administration of stevia extract
at 250, 500, 1000, and 2000 mg/kg.
Stomach, colon and liver DNA were not damaged.
As all studies showed negative responses, stevia extract and steviol are
concluded to not have DNA-damaging activity in cultured cells and mouse
organs. PMID: 12533916

Aspartame: The world agrees it's safe By Michael Carakostas, DVM, PhD
Director, Scientific and Regulatory Affairs, Coca-Cola
It is commendable that Carakostas mentions the core problem, albeit
disparagingly, and overlaid with multiple untruths: "During digestion,
aspartame yields a very small amount of methanol-- as do many other food
substances. The body converts this methanol to formaldehyde, which is
instantly converted to formate. Formate is quickly eliminated as carbon
dioxide and water."
Carakostas deceptively make claims, unsupported by research, that the amount
of methanol from aspartame is "very small", that many foods release as much,
and that little of the inevitable formaldehyde or formic acid toxic products
accumulate in body tissues. This executive, with a PhD in veterinary
science, is deceiving people about very serious multiple toxicities.
Thus, there is evidence here cited from 1973 to 2004 that research and
reviews by immense vested interests about aspartame must be scrutinized with
the greatest skepticism. The greatest Internet myth about aspartame is
this: "Aspartame is the most thoroughly tested food additive in history."

They conducted a double-blind study of patients, ages 18-55, who had
a medical diagnosis of classical migraines (normally having 1-3
migraines in 4-weeks), who were not on medications (other than
analgesics), and who suspected that aspartame had a negative effect on
their migraine headaches. The subjects were given 1200 mg daily,
aspartame or placebo, for four weeks, about 17 mg/kg. The placebo
group had no increase in headaches. Approximately half of the subjects
(5 of 11) who took aspartame had a large, statistically significant
(p = 0.02), increase in migraine headache frequency, but not in
intensity or duration, compared to baseline or placebo. Only 11 of
25 subjects completed the program: 8 dropped out, 4 began new
medications, 2 had incomplete records. They were at home.
Since 1/3 of the subjects dropped out, they may have been choosing
to avoid headaches-- were they unpaid? To achieve statistical
signifance with only 11 subjects hints that the incidence rate from
aspartame is very high, about 1/2, for migraine cases who believe
that they are hurt by aspartame.

Eight depressed patients, ages 24-60, and five non-depressed controls,
ages 24-56, employed at the hospital, were given for 7 days either
aspartame or a placebo, and then after a 3 day break, given the
opposite. Each got 2100 mg aspartame daily, 30 mg/kg bodyweight,
equal to 10-12 cans of diet soda daily, about a gallon. Despite the
very small number of subjects, the results were dramatic and
statistically significant. The eight depressed patients reported with
aspartame, compared to placebo, much higher levels of nervousness,
trouble remembering, nausea, depression, temper, and malaise. (For each
symptom, p<0.01) The five normals did not report strong enough
differences between aspartame and placebo to be significant.
Initially, the study was to be on a group of 40, but was halted by the
Institutional Review Board because of severe reactions among 3 of the
depressed patients.
Again, statistical significance with only 8 depressed patients:
"In this study, patients most often began to report significant
symptoms after day 2 or 3." The incidence rate is very high,
indeed, about 1/3. The most common symptoms are entirely typical
of thousands of case histories.

In their introduction, they comment:
"In addition, the FDA had received over 5,000 complaints as of July,
1991 in a passive surveillance system to monitor adverse side effects.
(17) Neurologic problems constitute the primary complaints in these
and several other case series, with headaches accounting for
18 to 45 %,depending on the case series reported. (17-19)"
Subjects, ages 18-57, were recruited who believed they got headaches
from aspartame, but were otherwise mentally and physically healthy.
They were paid $ 15 total, and were at home. Of the 44 subjects, 32
contributed data to the 38-day trials: a week of inert placebo, a week
of either aspartame or placebo, followed by a week of the opposite, and
then this two-week cycle repeated. The daily dose was about 30 mg/kg.
"The proportion of days subjects reported having a headache was
higher during aspartame treatment compared with placebo treatment
(aspartame = 0.33, placebo = 0.24; p = 0.04) (table 5)".
Of the 12 subjects not included in the data, 7 reported adverse
symptoms before withdrawing.
Again, statistical significance with a moderate number of healthy
subjects, willing to be recruited by a newspaper ad, who believed
aspartame hurt them. The number of headaches for each subject
for each treatment week are given: it appears that 4 subjects
had the strongest increase in headaches from the run-in week
or placebo week to their first week on aspartame, jumping from 0 to 5,
1 to 6, 1 to 4, 0 to 5 headaches per week. So, about 4 of the 44
healthy people recruited for the study, who believed aspartame hurt
them, had a stong increase in headaches from the first week of daily
asparame exposure, while 7 reported adverse symptoms before leaving,
a total of 11 out of 44, an incidence ratio of 1/4.
This is sky high, if we consider that, if the incidence ratio for the
about two hundred million users in the USA is 1 of 100, that is 2
million cases. It is plausible that the incidence ratio lies between 1
and 10 out of 100 for continuous daily exposure. These three flames
should have set off alarm bells, with extensive follow-up studies and
much more careful study of thousands of case histories. But these
little flares were adroitly smothered by thick blankets of industry
funded fluff:

Aspartame: Methanol and the Public Interest 1984: Monte:
Murray 2002.09.23 rmforall
Dr. Woodrow C. Monte Aspartame: methanol, and the public health.
Journal of Applied Nutrition 1984; 36 (1): 42-54.
(62 references) Professsor of Food Science [retired 1992]
Arizona State University, Tempe, Arizona 85287 woodymonte@xtra.co.nz
The methanol from 2 L of diet soda, 5.6 12-oz cans, 20 mg/can, is
112 mg, 10% of the aspartame.
The EPA limit for water is 7.8 mg daily for methanol (wood alcohol), a
deadly cumulative poison.
Many users drink 1-2 L daily.
The reported symptoms are entirely consistent with chronic methanol
toxicity. (Fresh orange juice has 34 mg/L, but, like all juices, has 16
times more ethanol, which strongly protects against methanol.)
"The greater toxicity of methanol to man is deeply rooted in the limited
biochemical pathways available to humans for detoxification.
The loss of uricase (EC 1.7.3.3.),
formyl-tetrahydrofolate synthetase (EC 6.3.4.3.) (42)
and other enzymes (18) during evolution sets man apart from all
laboratory animals including the monkey (42).
There is no generally accepted animal model for methanol toxicity (42, 59).
Humans suffer "toxic syndrome" (54) at a minimum lethal dose
of <1 gm/kg, much less than that of monkeys, 3-6 g/kg (42, 59).
The minimum lethal dose of methanol
in the rat, rabbit, and dog is 9.5, 7.0 , and 8.0 g/kg, respectively (43);
ethyl alcohol is more toxic than methanol to these test animals (43)."
"Fruit and vegetables contain pectin with variable methyl ester content.
However, the human has no digestive enzymes for pectin (6, 25) particularly
the pectin esterase required for its hydrolysis to methanol (26).
Fermentation in the gut may cause disappearance of pectin (6) but the
production of free methanol is not guaranteed by fermentation (3).
In fact, bacteria in the colon probably reduce methanol directly to formic
acid or carbon dioxide (6) (aspartame is completely absorbed before
reaching the colon).
Heating of pectins has been shown to cause virtually no demethoxylation;
even temperatures of 120 deg C produced only traces of methanol (3).
Methanol evolved during cooking of high pectin foods (7) has been accounted
for in the volatile fraction during boiling and is quickly lost to the
atmosphere (49).
Entrapment of these volatiles probably accounts for the elevation in
methanol levels of certain fruits and vegetable products during canning (31,
33)."
Recent research [see links at end of post] supports his focus on the
methanol to formaldehyde toxic process:
"The United States Environmental Protection Agency in their Multimedia
Environmental Goals for Environmental Assessment recommends a minimum
acute toxicity concentration of methanol in drinking water at 3.9 parts
per million, with a recommended limit of consumption below 7.8 mg/day (8).
This report clearly indicates that methanol:
"...is considered a cumulative poison due to the low rate of excretion
once it is absorbed. In the body, methanol is oxidized to formaldehyde
and formic acid; both of these metabolites are toxic." (8)...
Recently the toxic role of formaldehyde (in methanol toxicity) has been
questioned (34).
No skeptic can overlook the fact that, metabolically, formaldehyde must be
formed as an intermediate to formic acid production (54).
Formaldehyde has a high reactivity which may be why it has not been found in
humans or other primates during methanol poisoning (59)....
If formaldehyde is produced from methanol and does have a reasonable half
life within certain cells in the poisoned organism the chronic toxicological
ramifications could be grave.
Formaldehyde is a known carcinogen (57) producing squanous-cell carcinomas
by inhalation exposure in experimental animals (22).
The available epidemiological studies do not provide adequate data for
assessing the carcinogenicity of formaldehyde in man (22, 24, 57).
However, reaction of formaldehyde with deoxyribonucleic acid (DNA) has
resulted in irreversible denaturation that could interfere with DNA
replication and result in mutation (37)..."

"...the total amount of methanol absorbed will be approximately 10% of
aspartame ingested. An EPA assessment of methanol states that methanol, 'is
considered a cumulative poison due to the low rate of excretion once it is
absorbed. The absorbed methanol is then slowly converted to
formaldehyde...'"
"Reaction of formaldehyde with DNA has been observed, by spectrophotometry
and electron microscopy, to result in irreversible denaturation."
"DKP [from aspartame] has been implicated in the occurence of brain
tumors."

Consensus Action on Salt and Health
Substitute stevia (at health food stores).
Avoid all products with aspartame and MSG. Gradually reduce alcohol, sugar,
caffeine (coffee, cocoa, and teas), meat, fish, eggs, milk, butter, and
cheese, food additives and colors, fluoride, city water, salt and sodium.
Enjoy organic rice, beans, nuts, almond butter, vegetables, fruits, with
modest use of soy products and sprouted grain breads, flax seed and olive
oils, vitamins and minerals, 4-8 1,000 mg fish oil capsules, and fill your
jugs with deionized water.
